Hopefully these will help... I've been told, since I asked the old owner
about the new growth. He states the parent plant is a very
very old upright succulent (standing 3'+), on a single strong stalk,
that holds itself. It also has the flat pads at the top. This was an old
piece that had fallen off and started rooting itself in the parent plant's pot.

The plant very much reminds me of a Rhipsalis, but of course I don't
know. There are no thorny spikes. All soft tissue, even the new spikes
that are emerging. No low light, in bright indirect light, and outside now.

I do believe I was watering it to much and giving it to much fertilizer.
I'm thinking that's why the tips browned, or maybe too bright of light.

Thanks so much for your input...

@Shy_gardner I don't know if you use your cell phone, I use mine to take pictures. Whether I'm trying to take an up-close picture of my plants or my little puppy, I have to wait many seconds for the camera function to focus in on my subject (instead of the background) before I can capture a clear image. Hope this helps.
